The mitered return has a “return” on one or both sides that is used for an open staircase where the tread needs to hang over the edge. These also have the bullnose on them and the most common size for these treads are 11-1/2″ (13″ with the return) and anywhere from 48 to 96 inches.
Bullnosed Landing Tread
A landing tread is used on any part of your staircase that comes to a landing, that is where it has a turn or level change. The bullnose landing tread serves to give the edge a finished tread look. This can also be used on the edge of a balcony area. Usually coming about 6-1/2″ in depth with a 1″ nosing and a 3/4″ tread. They come in various lengths up to 8 ft.
